I'm getting a weird missing $ error in my bibliography

I've seen the solution Missing $ inserted issue to use \usepackage[strings]{underscore} but that conflicts with too many things in my actual paper so I'm hoping for something simpler.

  • When I compile your code on my system, I'm afraid I am unable to generate the error message you say you've encountered. – Mico Oct 30 '23 at 19:52
  • @Mico See here https://www.overleaf.com/read/ftgfzjsrzdwp#468519 – Hao S Oct 30 '23 at 19:55
  • Incidentally, one of the warning messages you're receiving is trying to tell you that you should be using the entry type @incollection, not @inbook, for the Karp1972 entry. – Mico Oct 30 '23 at 19:59
  • Thanks for providing this link. It looks like Overleaf is using an obsolete, and faulty, version of the llncs document class: version 2.20, 10 Mar 2018. In contrast, on my system (MacTeX2023, all updates applied), I find llncs 2022/09/05 v2.22 in the log file. Is there any chance you could switch to a TeX distribution that uses a more up to date version of the llncs document class? – Mico Oct 30 '23 at 20:05
